a "spidery opening into other worlds," but they sure aren't mysterious and attractive, that is unless you find a nasty, dark space under your house full of pipes, ducts, spiders, cat urine and in my case, some dead animal, attractive

A crawl space foundation means an elevated first floor system that is usually high enough off of the ground to crawl beneath. Piers are made up of 8” x 16” blocks, and the foundation wall is made up of brick and 8” blocks. The foundation wall contains foundation vents, which allow air to circulate throughout the foundation so that moisture does not build up.

Space between the ground and the floor of a house in which a person cannot walk upright. An enclosed crawl space is one not accessible from the outside of the house (except by a door or window) because the walls of the space protect it from the weather. A crawl space "open to the outside" is one that is accessible from outside the house--even though it may be covered by a trellis or lathwork, or some kind of brickwork that leaves space for circulation of air.

The space between the ground and the floor on houses not built on a slab or with a basement.
